Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the circuit diagram of the utility model control module；
Fig. 2 is the structure diagram of the utility model control system.
Embodiment
Embodiment 1：
A kind of fan of frequency converter intelligent control module, including ASIC plates, the first to the second solid-state relay；First to
Two Fan Drive Boards；The fan feedback loss alarm wire pin of ASIC plates connects the fan feedback loss alarm of the first Fan Drive Board
Signal acquisition pin, the feedback signal detection output pin of first Fan Drive Board and the fan of the second Fan Drive Board are fed back
Loss alarm signal acquisition pin is connected；The control terminal of the first to the second solid-state relay connects the first to the second fan respectively
The corresponding output end of driving plate, its coil are connected on the zero curve and firewire of fan power supply line respectively.
As shown in Figure 1, specific connection is connected for the X11 pins of ASIC plates with the first Fan Drive Board X8 pins, separately
Outside, first Fan Drive Board X3 pins are connected with the second Fan Drive Board X8 pins, and second Fan Drive Board X3 connects termination
Wire jumper.No. 4 pins of ASIC plates feed back loss alarm line for fan.
Two SSR-3P 6A solid-state relays are installed additional on the power cord that Fan Drive Board is powered to fan, so as to pass through
The break-make of two solid-state relays freely controls the start and stop of inverter fan, solid-state relay conductance messenger by frequency conversion
The digital output 2 of device controls, and solid-state relay working method turns on for frequency converter once starting, and frequency converter prolongs after stopping
When 180s disconnect automatically.So the fan start and stop of inverter can just be controlled by the digital output 2 of frequency converter completely, so that
Constraint of the driving plate to it is broken away from.Due to the artificial control that take part in inversion device fan, inverter is changed
The control structure of fan, so when holding state inverter fan does not turn, frequency converter can alarm No. 70 failures, i.e. inverter wind
Fan feedback is lost, and so frequency converter can be caused not start normally.By the research to frequency converter back panel wiring, ASIC plates are cut off
No. 4 pins into the X11 wiring of Fan Drive Board, just effectively avoiding frequency converter can not since fan feeds back loss alarm
The problem of startup.But the warning message lost due to eliminating fan feedback, weakens defencive function of the frequency converter to its own,
So also temperature protection of the host computer to transducer body is strengthened by writing for software program.
Embodiment 2：
A kind of fan of frequency converter intelligent control module, including the fan of frequency converter intelligently control described in more than one embodiment 1
Molding block, the corresponding network interface of each Fan Drive Board connect a machine.
The corresponding network interface of each Fan Drive Board connects host computer through interchanger.
The facility information of frequency converter is collected upper computer control system by network, and frequency converter is believed by programming software
The analysis and processing of breath, realize monitoring and protection of the host computer to frequency converter.
Host computer is made when inverter temperature reaches 90 degree by monitoring No. 313 parameters of frequency converter i.e. inverter temperature in real time
When being continued above 5s above, frequency converter automatic stopping.In frequency converter operational process due to fan goes wrong frequency converter cannot
Receive the alarm that inverter fan feedback is lost and stop, so as to cause the rise of inverter constant temperature to damage IGBT.Pass through
Program is added, stops frequency converter in time with program when inverter temperature is too high, realizes temperature protection of the host computer to IGBT.
The 5th of No. 322 parameters of upper computer control system real time monitoring frequency converter, that is, frequency converter abnormal conditions alarm, when
Detect this position from 0 be changed into 1 when, give one reset signal of frequency converter failure reduction point automatically, make its inverter fan feedback lose
Failure automatic shield is lost to reset.Due to the transformation carried out to frequency converter hardware, to prevent frequency converter due to that can not detect fan
And false alarm, cause frequency converter not start.So feed back loss alarm failure by the program fan of frequency converter that automatically resets and believe
Number, so as to ensure the stability that frequency converter starts at any time in the standby state.
The utility model combines the actual conditions of live the using and the reserved, frequency converter inverter not work under hot standby holding state
Make, do not produce heat, radiator fan need not operate completely, if the CRANK PULSES of fan be connected with frequency converter start and stop
Lock, realizes that inverter works when frequency converter starts, radiator fan brings into operation, and inverter fan is disappearing after frequency converter stops
Consume after inverter after-heat out of service after being delayed 3 minutes.So due to there was only the change of total amount half in daily production
Frequency device is operating, so the lost motion time of the inverter fan with regard to half can be reduced, equivalent in inversion device wind
Its service time at the scene is set to extend one times in the case that fan service life is certain, meanwhile, reduce the consumption of electric energy.
